Question

What are PPL and CPL (or XPL) images?

Answer

A PPL image is a Plain Polarized Light image. This is an image that is captured with a polarizer under the specimen and a polarizer (analyzer) above the specimen that are in-line with each other (0°).

A CPL or XPL image is a Crossed Polarized Light image. This is an image that is captured with a polarizer under the specimen and a polarizer (analyzer) above the specimen that are crossed with each other (90°).

The following images show an example of PPL and CPL scans of the same specimen.
